Application filed August 29, 1910. Serial No. 579,513.

of Michigan, have invented. certain new and useful Improvements inApparatus for the Manufacture of Capsules;and I do declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, referings, and to the characters of reference markedthereon, which form a part of this specification.

This invention relates to apparatus for manufacturing gelatin capsules,and consists in the construction, association, andcow operation of partshereinafter more fully set forth and pointed out particularly in theclaims. v

The object of the invention is to provide simple and eflicient meanswhereby the pins upon which the capsules are molded, may be dipped in abath of gelatin and thereafter moved through a suitable drier, fromwhich said pins are delivered to a stripping, trimming and joiningmachine and from said machine are conveyed to the dipping apparatus toagain mold the capsule parts thereon, the operation being continuous andautomatic.

The above object isattained by the mechanism illustrated in theaccompanying'drawings, in which: 7

Fig. 16 is a horizontal section through the lowershaft and sleeve shown in Fig. 15. Fig. 17 is an isometric view of thepin bar reversing ring. Fig. 18 is anelevation of said ring, showing apin bar in position therein. Fig. 19 is a similar view, showing a' pinbar reversed and a second bar in the ring in position for reversing.

Referring to the characters of reference,

and especially to theconstruction shown Fig. 1, 1 designates the dippingmachine through which pass the bars carrying the capsule mold pins, andwherein said pins are dipped in a gelatin bath, a detaileddescription ofwhich may be-found in Letters Patent No. 943,608, dated December 14,1909, and will not-be entered into herein. From the dipping machine, thebars of mold pins with the,gelatin capsules thereon are conveyed into adrying apparatus 2. At the a discharge of the drying apparatus, the barsof mold pins are engaged byv a reversing mechanism, by which said barsare reversed and'fed in pairs into a capsule stripping,

trimming and joining machine 3, wherein the caps and bodies of thecapsules are slipped from the mold pins, trimmed 'to the required lengthand joined in the manner illustrated and described in Letters Patent No.961,936 issuedJune 21, 1910; a detailed description therefore of suchmachine need not be repeated herein. After passing from the stripping,trimming and joining machine, the pin bars are reversed so as to a shaft30. It w cause the pins thereon to stand in the same direction and areconveyed in pairs .to the dipping machine to complete a cycle ofoperation.

The moldpins which form the caps and bodies of thecapsules are mountedto project laterally from suitable bars, and said bars are handled inpairs, each pair comprising a bar 4 carrying the relatively long pins 5"for formin the bodies of the capsules, and

shaft 11 carrying at its outer end a. ratchet wheel 12. Movement is imarted to said ratchet wheel and said sha 't by means of a pawl 13.carried by a reciprocatory arm 14 journaled on the shaft 11 and havingpivoted thereto at'1-5 the lower end of the connecting rod 16. The upperend of rod 16 is pivoted at 17 to an oscillatory disk 13 mounted on astub shaft 19 journaled in the frame. .Movement is imparted to the disk18 through the medium of a pitman 20, one end of which is pivoted tosaid disk, and the other end to a relatively small disk 21 on the end ofthe drive shaft 22 which crosses the frame -of the drying apparatustransversely and is properly journaled therein. llt will be seen that arotation of the shaft 22 will cause the disk 18 to oscil late and imparta similar motion to the arm 14 carrying the pawl 13, said movement ofsaid arm'causing the pawl "to engage the ratchet l2 and impart anintermittent movement to the shaft 11. To prevent a backward movement ofsaid shaft, there is employed a pivoted detent 13 ada ted to engage theteeth of said ratchet: 6n a projecting end I r of the shaft 22 is aworm'wheel 23 en aged by a worm car 24 on, a vertical shaft 25 carryinga rive pulley 26 adapted to receive a belt from a motor, not shown. The

shaft 22 also carries upon its projecting end a belt ulley 27. v A

Besi es the lower conveyer 9 upon which the pin bars are carried, thedrying apparatus contains an upper conveyer 28 passing around suitableulleys 29 on a transverse ill be understood that the speed of theconveyers 9 and 28'is regulated so that the mold pins with their-gelatin molds thereon shall remain in the drying apparatus a sufic'ientlen th of time to allow the gelatin to properly d and it will further beunderstood that the lowerconveyer carries the pin bars rearwardlythrough the drier and the upper conveyer carries said bars forwardly tothe discharge opening at, the front end. To elevate the pin bars fromthe lower conveyer to the upper conveyer there are'employed endlesschains 31 carrying the laterally projecting brackets 32 on which saidpin bars are adapted to rest on the elevating sides of said chains, asshown in Figs. 8 andt). The elevating chains pass around and are drivenby the rotation of suitable wheels 33 located on a horizontal shaft 34journaled in the lower part of the drying machine frame, and driven in amanner hereinafter explained, said chains at their upper ends passingaround similar wheels 35 on an upper horizontal shaft 36. Movement isimparted to the lower driving shaft 34 through the medium of a pinion 37thereon engaged by the teeth of a reciprocatory rack bar 38 mounted toslide in a guide 39, and pivoted at its upper end to the oscillatorydisk 18. Formed integral with the pinion 37 and mounted to rotateloosely therewith upon the shaft 34 is a disk 40. Pivoted at 41 to theinner face of said disk is a gravity pawl 42 adapted to engage the teethof a ratchet wheel 43 fast to the shaft 34. While the gravity pawl 42remains in engagement with the ratchet 43, the shaft 34 will'he turnedby each upward stroke of the rackbar 38, the return or downward strokeof said rack bar causing the pawl 42 to slip over the teeth of theratchet 43 without imparting movement to the shaft 34. To prevent abackward movement of the elevating chains, there is employed a pivoted'detent- 44 adapted to engage the and avoid the possibility of one endof the bar being lifted while the other still remained upon the lowerconveyer 6; To obviate this difficulty I have arranged to pre-' vent theoperation of the elevating chains until the pin bars are presented in astraight transverse position with respect thereto, by the followinprescribed mechanism Standing vert cally in the path of travel of thepin bars are the trip arms 45 and 46,

respectively, the arm 46 being-mounted on a rock shaft 47, and the arm45 being mounted upon a sleeve 48 rotatable on shaft 47.

Said shaft and sleeve each carry at the outer end thereof a curvedfinger 49 which embracesand normally bears against the free endof thegravity pawl 42 to hold said pawl gaging an extension thereof, as shownin Fig. 8. Under normal conditions, thefingers 49 holdthe pawl 42 fromengagement with the ratchet 43, so that a movement of the rack bar 38will impart no motion to the shaft 34. As the pin bars are carriedalong, however, by the lower oonveyer 9, they will be caused to engagethe trip arms 45 and 46 and will turn the shaft 47 and sleeve 38sufiiciently to carry the fingers 49 thereon away from the pawl.42,allowing said pawl to engage the ratchet 43 and. impart movement to theshaft 34 through the medium of the rack bar 38. It will be un.-,derstood that both of the fingers 39 engage the pawl 42 so as to hold itfrom engagement with the ratchet wheel 43, making it necessary thatboth, fingersbe actuated to carry them from contact with the pawl inorder tio permit said pawl 42 to become/operative y associated with theratchet. For that reason, should a pin bar be conveyed, to the elevatingchains with one endin advance of the other, the elevating mechanismcannot be set in operation until said bar is transversely alined withrespect to said chains, as contact of both ends of said bar with thetrip arms 45. is necessary to set in motion the elevating mechanism. Asthe pin bars are elevated by the. intermittent movement of "the chains31 to the level of the upper conveyer 28,-they are successively removedfrom the carrying'brackets 32 of said "chains by the reciprocatory arms51 which are hung from a rock shaft 52. Upon a projecting end of saidshaft is a crank arm 53 with which is flexibly connected the upper endof a connectingrod 54, the lower end of said rod being pivoted to theoscillatory disk 18', so that as the disk oscillates,

. the shaft 52 is rocked and the arms 51 are swung to slide the pin barssuccessively from the brackets of the elevating chains onto the upperconveyer 28, as clearly shown in Figs. 8 and 9. As-the elevatingmechanism handles the pin bars sequentially their paired relation ismaintained and they are presented to the upper conveyor moved alonghorizontal tracks to the verti-' cal guides through which they are fedinto the stripping, trimming and joining machine, which, forconvenience, will be hereinafter referred to as the capsule or joinmgmachine y In describing the mechanism for deliver-z 'ing the pin barsfrom the drier to the capsule machine, reference will be made moreparticularly to Figs. 2, 3, 4, 5, 10 and 11. At the discharge end of thedrying apparatus is located a box or case 55 which is preferablyquadrangular in form and within which and upon which is mounted the pinbar reversing mechanism. Within the case '55 is a track 56 extendingalong each side thereof which is made to register with the discharge endof the upper conveyor of the drying apparatus,

so that by the movement of said c'onveyer, the pin bars are deliveredonto'said track and are caused to slide thereon toward the outer end ofthe case, said bars being disposed in,pairs and arranged so that thebars carrying the body pins and the bars carrying the cap pins, shallalternate. Disposed at the outer or discharge end of the case 55 is anoscillatory ring 57 mounted to oscillate in the arc of a vertical circleabout a horizontal axis, the distance of travel of said ring beingapproximately equal to about one-quarter of" a complete circle. Saidring is supported on its lower side by the flanged travelers 58, and atits upper opposite directions in reciprocal succession,

as hereinafter explained. In the inner arc of the ring 57 is a pair ofdiametrically opposed channels 63 adapted to receive the opposite'endsof a pin bar to cause said bar to lie diametrically of the ring withinthe plane thereof. Also formed in the inner are of the ring 57 is a pairof channels 63* disposed side by the flanged travelers 59. Said at rightangles to the channels 63,and also adapted to receive the ends of a pinbar. As before 1 stated, the movement of the upper conveyer of thedrying apparatus carries the pin bars onto the track 56 in the case 55,the

ends of-said bars resting on "said track and Y the pins thereofprojecting upwardly, said bars being arranged in pairs, wherein the barscarrying the body pins and the bars carrying the cap pins alternate.When the ring 57 is at rest, it is always in a position to cause onepair of the. channels 63 or 63 therein to register with the track 56, asshownin Fig. 17, so that bv the movement of the upper conveyer of thedrying appae ratus; the outermost pin har'on the track 56 will be causedto slide from said track and into said registering channels in saidring,

at which time movement is imparted to said bars are urged alongthe'track 56, one of said bars during each period of repose of the, ring57 is caused to enter the pair of channels 63 vor 63 which may at thattime register with said track, so that a -pin bar when lying in eitherof the pair of channels in the ring will extend diametrically there-- offreefrom the track 56. Assuming that the ring is in the position shownin Fig. 17,

a pin bar will be moved from the track 56.

into the pair of channels 63, a position of parts illustrated inFig. 18,and said ring will be rotated approximately one quarter of a turn to theright, a movement which will carry the-bar 6 to the position shown inFig.

7 19, in which position the ends of said bar register with a pair ofchanneled track members, comprising an upper track member 67 and a lowertrack member 68. This position of the ring will causethe channels 63therein to register with the track 56 in position to receive the ends ofa succeeding bar which will be carried thereinto by the operation of theupper conveyer, as before described. As a succeeding bar moves into thechannels 63 said entering bar, which will be one of the bars 4, willengage the vertical bar 6 and force it out of the channel 63 so that itsends will enter the channels in the tracks 67 and,68; the arrestingshoulders 66 on the brackets 64 preventing the vertical bar 6 beingforced so far into the "channeled track members 67 and 68 as-to allowthe entering bar t to pass too far through the ring 57 so as to assumean incorrect position therein. The ring 57 willthen revolve to the leftapproximately one qtu'arter of a turn so as to carry the pin bar-floayertical position with the ends thereof in registering alinement with apair of channeled tracks, comprising an .upper track 69 and a lowertrack 70. It will be noted on referring to the drawings of the ring 57that said ring carries opposed lateral flanges 71 and 7 2, the

flange '71 having the cam faces 73 and 74;

and the flange 72 having the cam faces 75 and 76.- Tt will also be notedthat these cam faces on the flanges 71 and 72 lead respectively from themargins of the channels 63 and 63 in the inner face of the ring;vtherefore, after a pin bar, as bar 6 in Fig.-

19, shall have been caused to enter the horizontally extending trackmembers 67 and 68, and. the ring 57 shall have begun its rotation to theleft, the cam faces 7% and 76 will engage the opposite ends of the pinbar pulley 27.

and urge it horizontally along the horizontal track members 67 and 68 inthe channels of which the ends of said bar lie. It will also .be notedthat this return movement of the ring carries the arresting shoulders 66away from the pin bar so as to leave it free to move horizontally insaid track members. The same operation is repeated with respect to thesucceeding bar 4, which by the rota-' tion of the ring to the left, iscarried into registering alinement with the channels in the trackmembers 69 and .70 so that the succeeding bar which enters thechannels63 of the ring will slide the bar-4 outwardly into the channeled trackmembers 69 and 70 un til arrested by the abutment shoulders 66 of thebrackets 65, leaving said bar in such position that a succeeding rotarymovement to the right will cause the cam faces-73 and 75' of the flanges71 and 72 to engage said bar and move it horizontally along thechanneled track members 69 and 70; this operation being repeated asoften as the ring 57 oscillates, causing the bars 4 and6 with their capand body pins 5 and 7 respectively, to be fed along their respectivehorizontal track members and to the vertical guides 77 and -7 8, downwhich they are directed to thecapsule machine, As the bars having thebody pins and the bars having the cap pins must be fed intov the capsulemachine at different points and with their pins projecting inwardly, thenecessity of reversing said bars in reciprocal succession and feedingthem to the capsule machine from the drying apparatus by means of theoscillatory ring, will b understood, the bars being handled in pairs sothat the bars carrying the cap and body pins, respectively, shall be fedto the machine in equal numbers.

The mechanism for imparting the necessary reciprocation. or oscillationto the ring 56 and the means for controlling the operation of saidmechanism so as to prevent the o-peration thereofexcept when a pin baris in proper position within said ring, will now be described withreference more particularly to Figs. 4, 5, 1'0 and 11. As before stated,the ring 57 is driven through the rotation of the shaft 62 carrying thepinion '61.

which meshes with the teeth 60 of said ring. Mounted uponthe shaft 62are the loose beveled gears 79 and80 which are in constant mesh with thebeveled gear 81 on a shaft 81 journaled to the lower side of the -case55 and driven by means of, a pulley 82 there'on by a belt 83 ,(see Fig.,1) from the On'the hub of gear' wheel 79 are the jaw members 84c, andon the hub of gear wheel 80 are similar jaw ,members 85.

Splined to shaft 62 is a slidable clutch collar 86 having at its endsjaw members 87 and y 88, respectively, adapted as said collar is shiftedlongitudinally on said shaft to engage the jaws of'the gears 79 and 80,causing the shaft 62 to turn in opposite directions in reciprocalsuccession, accordingly as said clutch collar is caused to engage one orthe other of the jaws of said gears, forming in effect a reversingclutch through the medium of which the direction of rotation of theshagt 2 is successively changed. The

clutch collar 80 is actuated through the medium of a sliding bar 89carrying a yoke 90 which engages in a channel 91 therein, whereby saidclutch collar may be shifted on the shaft 62 as the bar 89 isreciprocated. The bar 89 at one end is provided with a rectangular head92 in which is formed a longitudinal slot 93. Loosely mounted on a stubshaft '9atis a swinging arm 95 in which is set a pin 96 which liesfreelywithin the slotted opening 93 of the bar 89. The outer end of the arm 95is provided with the inclined c'am faces 97'and 98 which converge to' apoint 99, the diverging terminals of-said cam faces each terminating ina curved recess 100. Iivotally mounted at 101. is a swinging arm 102,the free end of which is connected by a strong coiled spring 103 to afixed part, as at 104. Carried at the free end of the arm 102 is anantifriction roller 105 adapted to roll in contact with the cam faces 97and 98 of the arm 95 as said arm swings on its pivot.- or fulcrum, saidroller being at all times held forcibly in engagement with one or theother of said cam faces by the tension of the spring 103. On the end ofshaft 62 is a worm gear 106 which meshes with and is adapted to turn asector gear 107 loosely carried on the stub shaft 94 and adapted to beoscillated in the arc of a circle by the rotation of the worm 106.Projectingfrom a face of the cam 95 is a pin 108 which stands in thepath of the 'pins 109 and 110, respectively, projecting from a face ofthe sector 107 to successively engage the pin on the arm 95, and swingsaidarm from side to side, at the limit of movement of said sector inopposite directions. The sliding bar 89 through the medium of which theclutch collar 86 is actuated, is normally lockedagainstlongitudinalmovement by the locking boltslll and 112'whose inner ends are supportedin the bearing 113 through which the sliding bar 89 is adapted to slide,the inner ends of said lockingbolts normally engaging in acircumferential channel 111 in said bar. When the locking bolts areengaged in the channel of the bar 89, it is held against longitudinalmovement in either direction and the parts have such relation. that whensaid bar is so locked, the clutch collar 86 will bein a neutral positionfree from engagement with the clutch. jaws 84 and 85 of the gears 79 and80, leaving said gears free to revolve upon the shaft 62 withoutimparting a rotary movement thereto.

. 126 and 132 lie in the plane 0 The locking bolts 111 and 112 areactuated by the crank arms 115 and 116, respectively, mounted uponvertically disposed rock shafts 117 and 118 suitably journaled at theside of the case, said crank arms having a jointed vsaid arms engagingsaid bolts are constantly urged inwardly by means of the coiled springs120 which are confined between the sides ofthe case and an extension ofsaid arms, as clearly shown in Fig. 10. Movement is imparted to the rockshafts 117 and 118 to actuate the locking bolts, through the medium ofthe crank arms carried by said shafts and engaging said bolts, by meansof the cranks 121 and 122 mounted thereon, respectively, and shown moreclearly in Fig. 1. To the free end of crank 121 is pivoted a connectingrod 123, said rod being in turn pivoted to a lever 124 fulcrumed at itscenter and having a jointed engagement, as at 125, with a tri pingplunger 120 mounted to slide horizontally in a suitable support 127 atthe end of a bracket 128 which projects forwardly from the case andcarries said parts. By an outward pressure against the tripping plunger126,-the lever 124 will beoperate'd to turn the rock shaft 117 throughthe me dium of the connecting rod 123'and crank 121, thereby swingingthe crank arm 115 against the action of the spring 120 to withdraw thelocking bol-t 111 from the channel 114 in the bar 89. In like mannermovement is imparted to the rock shaft 118 through the medium of aconnecting rod 129 pivoted to the crank 122 and to a'lever 130 fulcrumedat its center and havin a jointed engagement at 131 with a trlppingplunger 132 mounted to slide in a suitable support 133 at the outer endof a bracket 134 projecting from the frame or case and carrying saidparts. An

be noted that both of the bolts lock the bar 89 against longitudinalmovement, and that it is necessary to retract both of said bolts torelease said bar. It will further be noted that the inner ends of thetripping plungers I the track 50 upon which the pin bars travel, andalso in the plane of the pair of channels in the ring 57' which arehorizontally disposed when said ring is at rest. The purpose of thisarrangement is to control the'rotary movement of said ring by theposition of the pin bars therein to prevent the possibility of said ringbeing rotated until each succe have been properly entered d positionedtherein. Should one of the pin bars enter the ring from the track 56with .one of its ends in advance of the. other, the ring 57 will notturn until said bar lies in perfect transverse alinement in the ring atright angles to the axis thereof, for the following reaso'nz-Should oneend of a pin bar enter the ring in advance of the other, it will engageone or the other of the tripping 'plungers and actuate the mechanism towithdraw one or the other of the locking 'bolts from engagement with thebar 89. The other locking bolt will still'vremain in locking engagementwith said bar, preventing any movement thereof until the other plungeris tripped which will not occur until the angularly positioned bar shallhave been urged forward so as to causeits lagging e'nd to actuate theother tripping plunger,

at which time, because of the position of said plungers, the bar willlie in straight transverse position within the ring. Upon the release ofthe locking bolts 111 and 112 the sliding bar 89 will be free to" movein either direction and will be moved in a directionin accordance withthe position of the reversing mechanism which controls the momement ofsaid bar at the time said bar is released. Should the lockingbolts beactuated to release the sliding bar when the parts are in the positionshown in Fig. 10,

The shaft 62 will remain at rest until thetripping plungers126 and 132 are again actuated to retract the locking bolts 111 and 112when the' tension of the spring 103 will crowd the antifriction' roller105' of the arm'102 against the cam .face 97 of the.

collar 86 into engagement with the clutch jaws 85 of the gear 80,thereby locking'said gear to the shaft through saidclutch collar andreversing the direction of rotation of the shaft 62, which movement willcause the sector gear 107 to swing back in the opposite directionandwill carry the pin 110 thereon into engagement with the pin 108011 thearm 95 and swing said arm so as to cause the antifriction roller on thearm 102 to ride over the point 99 andengage the opposite cam face 98 ofsaid arm 95, the force of the spring 103 after said antifriction rollershall have passed the point 99, drawing said roller against saidcam face98. will urge the arm 95 quickly over and will slide the bar 89 throughthe engagement-of the pin 96 'on said arm with a terminal of'tlie slot93 in said bar and withdraw the clutch collar 86 from engagement withthe clutch jaws or members 85 of the gear 80, thereby again stopping therotation of the shaft 62, a position in which said'partsv remain untilthe tripping plungers 126 and 132 are again actuated to withdrawthelocking bolts from the channel 114 in the bar 98, when said bar willagain be shifted through the medium of the spring 103 to again carry theclutch oretta description of the feeding of the pin bars from the dryingapparatus to the capsule machine and reversing them so that the pins onsaid bars shall project inwardly as they are fed througn' said machinein position to be properly acted upon by the stripping mechanism,through the medium of which the caps and bodies of the capsules arestripped from the mold pins of the pin bars, an operation fully setforth in the before mentioned Letters Patent No. 961,936.

From the capsule machine the pin bars,

, after the caps and bodies have been stripped therefrom, are restred totheir original horizontal position in pairs with the pins projectingupwardly in the following manner, reference being had more particularlyto Figs. 2, e, 7, 12, 13, 14, 15 and 16 :-The

vertical guides 77 and 78 down which the pin bars are directed into thecapsule machine extend vertically through said machine so as to directsaid bars to the lower reversing mechanism, wherein they are re- 7turned to a horizontal position with their pins projecting upwardly andare arranged in pairs, comprising a bar of body pins and a bar of cappins, a relation which is maintained while said bars pass through thedipping machine. and through the drying apparatus. The lower pin barreversing and pairing mechanism is driven from a shaft 135- of thecapsule machine rotated through the medium of a belt pulley 136 andcarrying at one end a beveled gear 137 which mesheswith a pinio 138 onthe upper end of a short vertical shaft 139. The

lower end of shaft 139 carries a beveledslidable clutch collar 14;")having at its ends jaw members adapted to engage the jaW members,respectively, of said gears. Clutch collar 145' is provided with aperipheral channel 146 in which engages the end of areciprocatory-shifting rod 147 adapted by a longitudinal movementthereof to shift the clutch collar 145 successively into engagementwiththe clutchmembers of the gears 141 and 142 to effect a reverse rotationof the shaft 143 in reciprocal succession. The

shaft 143 has mounted thereon the worms.

148 and 149 provided with right and-left threads, respectively. Meshingwith said worms are the isector gears 150 and 151 mounted respectivelyupon rock shafts 152 and 153, whereby as the shaft 143 is rotated, saidsectors are swung in opposite di 155, the opposite end of said rod beingivotally attached to the depending end, 0 an arm 156 formed integralwith a cam plate 157- which hangs loosely from the rock shaft 152. Onthe lower side of the plate 157 are the inclined cam faces 158 and .159;said faces converge to a point 160 (see Fig. 13). Pivoted to the lowerend 'of a depending post 161 is an arm 162 which lies in a substantiallyhorizontal plane and carries at its free. end an antifriction roller 163which is adapted to engage the cam faces 158 and 159 of the plate 157,and is at all times held forcibly against one or' the other of saidfaces by means of the coiled spring 164 attached at one end to theterminal of said antifriction roller, and at the-other end to' the hub165 of the plate 157. The crank arm 154. is loose upon the shaft 153 andsaid crank arm, whereby said armis swung a short distance at the limitof movement of the shaft/153 in each direction. Projecting from the sideof the cam plate 157 is a pin 170 which lies in the horizontal slot 171formedin the head 172 of the shifting rod 147 whereby the reciprocatorymovement of the cam plate will cause said pin to successively engage theterminals of the .slot 171 and shift the rod 147 in a manner to causethe clutchcollar 145 to suecessively engage the clutch members on thehubs of the gears 141 and .142, thereby imparting. to the shaft 143 anintermittent rotation in opposite directions. 'The normal position ofthe reversing mechanism withthe shifting rod 147 in repose isillustrated in Fig, 13, in which position the shifting rdd is locked byengagement of the detents- 173 and 174, shown more clearly in Fig, 15,with the shoulder 175 on the head i of the shifting rod 147 and theclutch collar is held in a neutral position upon the shaft 143 free fromengagement. with the clutch members on the hubs of the gear wheels.141and. 142. It will .be noted on re.-

ferring-to ig. 13' that in the position of parts justdescribed, theantifriction roller 163 is urged against the cam face 159 of.

the plate 157 by the tension of the spring 164, thereby crowdingsaidplate toward the left and causing the pin 170 therein to engage theterminal of the slot 171 at the end of the rod 147, whereby the shoulder175 on the head of said rod is held with force against the ends of thedetents 173 and .174. In this position, thetmechanism is locked andcannot be started until said detents are tripped to raise them fromengagement with the shoulder 175 of the shifting rod."

Provision is made for tripping the detents to release the shifting rodin the following manner :Detent 173 is mounted on a rock shaft 176suitably journaled and carrying a crank arm 177 fast thereto. Attachedto the outer end of said crank arm is a connecting rod 178 which is alsoattached to a crank arm 17 9 on the lower shaft 180 carrying at its enda tripping finger 181. Detent I attached to a connecting rod 184 whichis in turn attached to a crank arm 185 on a lower the swinging arm 191mounted on andmov 174 is mounted upon a sleeve 182 which is. j ournaledupon the shaft 176, whereby said' detents are permitted to moveindependently. On the sleeve 182 is a crank arm 183 sleeve 186 journaledon the shaft 180. Fast to the end of the sleeve 186 is a tripping finger187. Depending from the frame of the capsule machine are two curvedtracks 188 and 189 which describe a quadrant and stand in oppositedirections. The tripping finger 187 extends through an opening at thelower end of track 189 just below the depending end of the swinging arm190 carried on and movable with the rock shaft 152, while the trippingfinger 181 extends through an opening in the lower end of the track 188just below the depending end of able'with the rock shaft 153. The pinbars 4 and 6 when they fall from their guides 77 and 78, respectively,after passing through the capsule machine, drop in a.vertical posi--tion onto their respective tracks 188 and 189, as clearly shown in Fig.2, in-which position said bars lie in front of the swinging arms 190"and 191. The pin bar 4 in itsfall strikes with its lower end thetripping finger 187, thereby depressing the raised end of said fingerand turning the sleeve 186. This movement swings the crank 185 and thecrank 183 through the medium of the connecting rod 184, whereby theupper sleeve 182 is turned and the 'detent 174 left free from engagementwith the shoulder 175 of the shifting rod 47. In like manner the fall ofthe bar 6 will cause the lower end thereof to strike and depress thefinger 181, thereby turning rock shaft 180- and swinging the crank arm179 which imparts a similar movement to the crank arm 177 through theconnecting rod 178, whereby the shaft 176 is turned to lift the detent173 from the shoulder 17 5 of the shifting rod 147. When both of saiddetents are thus raised from engagement with said shoulder, the tensionof the spring 164 which holds the antifriction roller 163 forciblyagainst the cam face 159 of the. late 157, will swing said plate to theleft see Fig. 13) and cause the pin 170 thereon lying in the "slot 1710fthe" bar 147 to shift said bar longitudinally and carry the clutchcollar 145 into engagement with the clutch members on-the hub of thegear 142, when said gear will impart to the bars are carried onto ahorizontal track on which they are conveyed to the dipping ma-.

chine by a feeding mechanism hereinafter the shafts 152 and 153 inopposite di- 1 explained. When the arms or sweeps 190 and 191 shall havereached the limit of their upward travel to carry the-pin bars into ahorizontal position, the shaft 153 by the rotation :thereof will havecaused the extension 167 on the collar 166 to have engaged the shoulder168 on the hub of the arm 154 I and will have swung said arm andactuated the cam plate 157 to carry the point. 160 thereon past theantifriction roller 163, when the tension-stored in the spring 164drawing said roller forcibly against the cam face 158 of said plate,will shift said plate suddenly to the right from the position shown inFig. 13, causing the pin 17 0 carried thereby toengagethe terminal ofthe-slot in the bar 147 and shift said bar to the right'such distance asto carry the clutch collar 145 from engagement with the clutch memberson thehub of the gear 142 into engagement with the clutch members on thehub of-the gear 141, thereby disengaging the gear 142' from the shaft143 and connecting gear 141. with said shaft. This change of position oftheclutch 145 causes the shaft 143 to at. once revolve in the oppositedirection, whereby the sectors 150. and '151 are returned to their firstposition, rocking the shafts 152 and 153 and returning the arms 190 and191 on said shafts-respectively, back to a-vertical position, as shownin Fig. 6-. The return movement of the shaft 153 will cause the lateralprojections 167 on the collar 166 on said shaft to engage the shoulder169 (see Fig.

13) on the hub of the arm 154 and swing said arm to the right, said armcarrying with it-the arm 156 through the medium of the connecting rod155 and actuating the cam plate 157 to cause the antifriction roller 163to ride from the cam face 158 thereof past the point 160 intoengagement'with the cam face 159, when the force exerted by the spring164 will shift the plate 157 quickly to the left, causing the pin 170carried thereby to shift the rod 147 and withdraw the clutch collar 14.-from engagement with the clutch members on the gear wheel 141. As therod 147 is drawn to the left, it is arrested by the engagement of theshoulder 175 thereon with the ends of the detents 17 3 and 174 at apoint in its longitudinal travel when the clutch collar 145 shall havebeen moved thereby to the neutral position upon the shaft 143 midwaybetween the clutch members on the gear wheels 141 and 142, a position inwhich both gear wheels are disconnected from the shaft 143, therebystopping the rotation thereof. The detents 173 and 174 after beingtripped by the pin bars striking the tripping fingers 181 and 187 torelease the shifting rod 147, are returned to their normal positionafter the pin bars shall have been moved from engagement with saidfinger by means of the fiat sprin' s 192 and 193, respectively, thetension of w ich is sufficient to actuate the connected parts and returnthe free ends of said detents into the path of the shoulder 175 of theshifting rod 147, so that upon the return of said rod to the left, itwill be arrested by said detents to hold the clutch collar in theneutral position until said detents are again tripped. it willthereforebe apparent that the movement of the sweeps or arms 190 and 191 whichcarry the pin bars upwardly on the curved tracks 188 and 189, is from avertical to a horizontal and back'to, a vertical position, said barsbeing arrested each time they are returned to the vertical positionshown in Figs. 2 and 6.

At the time the pin bars are discharged from the guides 77 and 78 of thecapsule machine, one may be slightly in advance of the other and infalling will trip its detent' actuating finger. Should the mechanismstart to operate when tripped by the first bar discharged from thecapsule machine guide before the other. bar shall have been sodischarged, serious damage to the machine would follow. By providing forlocking the hifting rod 147 by means of two detents, both of which mustbe tripped to release said rod, the mechanism cannot begin operationuntil both pin bars shall have been discharged from the guides of thecapsule machine and are free to be swung to a horizontal position by thearms 190 and 191. When the pin bars 4 and 6 shall have been swung to ahorizontal positionby the sweeps or arms 190 and 191,

their ends are caused to lie upon a horizontal track 194 whichcommunicates with the track 8 (see Fig. 1) leading to the dippingmachine. To carry the pin bars from their position on the swinging arms190 and 191 after they shall have attained a horizontal position, thereare employed the feeding slides 195 which are located parallel with thetrack 194 and upon which are pi votally mounted the spring actuated dogs196. Said slides are provided on one edge with rack teeth 197 which meshrespectively with the pinions 198 on the upper end. of the verticalshafts 199, each of said shafts carrying at its lower end a beveled gear200 which meshes with a beveled inion 201 on the shaft 143. By reason ofsaid pinions and gears the rack-engaging pinions are rotated to causethe slides 195 to travel forward and backward in suitable guides in theframe, whereby the dogs 196 thereon will be caused to successivelyengage the opposite ends of the pin bars and move them along the track194, the arrangement and operation of parts being such as to presentsaid pin bars in pairs to the dipping machine, ach pair comprising a bar4 car rying the body pins 5 and a bar 6 carrying the cap pins 7, asshown at-the upper part of Fig. 7. The operation of the slides 195through the medium of the spring actuated dogs carried thereby, feed thebars horizontally along the track 194 until they are received by themechanism of the dipping machine, wherein the pins of said bars aredipped into the gelatin bath and from whence said pin bars are conveyedto the drying apparatus, as'before described, thus completing theoperation; said bars with their mold pins moving continuously throughthe drying apparatus, the capsule machine, the dipping machine, and backto the drier, during all of which travel said bars are handledautomatically-and their relative position so preserved as to maintainthe paired relation between the bars having the cap pins and the. barshaving the body pins, so that each time the bars are returned to thecapsule machine, they are properly directed to their respective guidesand are caused to pass through said machine in their proper relativeposition.
